CULTlVATOR.

SPECIFICATION forming part of Letters Patent No. 355,631, dated January 25, 1867.

Application tiled Jnly 1.4, 1886. Serial No. 208,034, (No model.)

To @ZZ wrom iz? may concern.-

Be it known that I, PETER Fnicnn'rfrn, of Sheridan, Placer county,`State of Californie, have invented an improvement in Cnltivators; and l hereby declare the following to he e full, clear, and exact description of the same,

My invention relotesto that class of agricultural implements which nre used for cultivoting the ground, and which are known, eccording to slight differences of construction, as coltivatore herron's, Sac.

lily invention consists in the iniprovemenis hereinafter folly described and claimed.

Referring to the accompanying drawings for a more complete explanation of my invention, Figure l is n plan of my cultivator. Fig. 2 is n side elevation 0i' seine. Fig. 3 is e section of the tooth-securing casting C.

A is the frame of the machine. This is inode of dat here n, of iron, set on edge. Each bor is heut ont of line et or about its middle, and they ere so iitted together that each hor is connected at one end with the har on one side, and nt the other with the heir on the other side. In order to explain this arrangement more perfectly, l coll attention to the number of hers shown in the drawings. They number Six, and observing them from the front of the machine it will he seen that they are arranged in pairs, the members of each pair lying close together from their forward en ds hack to where they begin to hond, from which point they diverge, the interior ones meeting the adjacent ones of the next pair, whence they extend in nerf-formed pairs to the rear of the machine. Looked et from the front, the frame presents the appearance of e number of Ys i set alongside euch other. The bers of the frame are secured together by the cross-hars 51.',wl1ich lie in pairs above and below the hars o, and receive bolts a2, the tightening np of which clamps the Trame-bars. They are further held together hy the loolts which secure the tooth-hearing castings, as I shell now explain.

B are castings, which nre socketed to receive the teeth C. These castings are made whereby they nre held in place. These toothbearing castings are placed along the frame hars et ditterent points, and each is out of line with the other, this position being possin ble by reason of the bend of the here, and also by placing them upon opposite sides of the hars. It will he seen that the bolts l1', where they pass through the adjacent portions of the here a, serve to hold seid hars together.

The teeth C are passed through the sockets of the castings, end are secured therein by the set-screws c, whereby they may be tightened in en y position desired. The teeth may be of any suitable character, depending upon the use to which the machine is to he put. Thus for ocnltivetor I would use the ordinary sharpcned binde, while for a barrow n. simple tooth would he employed This device for fitting the teeth or blades to the machine is e very eiective one, in that the teeth :ire sccurelyheld against the strain, which has a. tendency to loosen them, end they can be readily placed in posi tion and ns quickly removed. If the castings shonld become Worn, they may he thrown aside without great loss, which is on improvement over the ordinary iron'toothed horrors, in which the teeth pass directly through the hers of the freine and have to he wedged constently to keep them tight- Mounted in hearings d on the front of the frame is n. roclnsheft, D, the cndsof which are provided with vertical cranlosocliets d', in which are fitted the standards c of the front Wheels, E. The vertical adj nstinent of the Wheels E is effected by means of the collars e on the standards, which are set by screws e", whereby their position may he changed with relation to the sockets d.

The collars are not set u p close enough to the sockets to prevent the free rotation of the' Wheel-standards in any direction, for by this movement the frame is enabled to ineke its turn. lrIcnnte-d in hearings f on the reef of Ithe frame is a rock-shaft, l?, the ends of which have crossnrms or crenksf. To these crankarms are bolted the standards g oi' the rear wheels, G. A series of holes, g', are made in the standards, whereby their vertical adjustment is effected. At about the center of the frame A is pivoted a lever, H, the movement of which is controlled and iiXed by a slotted curved rack,rh, and a springactuated pawl, h. The lever is connected with the frontend rear rock-shafts through the links I, pivotedto the lever, and the cranks l on the shafts, the connection being an adjustable one, by means of the series of holes i, made/in the links and in the cranks of the shafts.

The lever and rack, though they may be secured upon the frame in other ways, are here shown as secured to brace-bars J, runninglongitudinally of the frame above and below and bolted together,'as shown. These bars add vstrength to the frame, and are not in the way of any of the other parts.

By operating the lever H the shafts D F are rocked, whereby the wheels are thrown back and the frame lowered to project the teeth the required distance into the ground. By rcversing the lever they are raised.` again and can be carried clear of the ground, which is of advantage when working in orchards in allowing the machine to pass a tree without injury.

The rotary movement of the standards of the front wheels enables the machine to make its turn, and provides for the use of four wheels upon the machine, instead of the usual nun1- ber threw-namely, two main wheels and a single steering-wheel.

`When the machine is used as a simple harrow, I omit the wheels and the adjusting devices,` using only the frame and the proper teeth Xed in the castings, as described. Light plow-teeth may be also used in the machine when the work requires it.

The frame constructed as described is strong and yet simple and economical.

The clevises being attached to the front of each pair of bars a equalizes the draft over the entire frame. It is apparent that the width of the frame may be greater or less, as desired,

by simply adding to or taking away from the number of bars c, and also that by reversing the bars the wide part of the frame may be in front and the narrow part behind. When working in a vineyard, I would arrange the wheels inside of the outer bars of the frame, so that they should not come in contact with the vines.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. In a cultivator, the frame A, consisting of the flat bars a, set on edge, each bar being bent out of line` at or about :its center, and diverging, so as to be connected with the ad-` and having a grooved face, b, lfor tting the. sides of the same, and the teeth C, passing` through a socket in the casting and secured therein, substantially as herein described.

3. In a cultivator, the toothed frame A, in combination with the wheels E at the forward end, said wheels having standards e, and the wheels G at the rear corners, `having standards g, the roclcshaft D on the forward end of the frame, having end sockets, d', in which the l standardsof the forward wheels are adjustably pivoted, the rockshaft F on Ythe rear end of the frame, having the crank-arms f, to

which the `standards of the rear wheels are adjustably connected, the pivoted lever H, having the pawl and ratchet, the links I, the cranks I of therock-shafts, and an adjustable connection between ythe links and cranks, substantially as herein describedr 4. A cnltivator comprising the `frame A, made of the bent flat bars a, the` transverse bars c', and the longitudinal bracebars J, the removable socketed castings B, the teeth C, adjustably tted to the castings, the wheels E G at the corners of the frame, the rock-shafts D F, having cranks at eachiend, to which the` wheels are adj ustably connected, as described, the lever H, the cranks I of the rock-shafts, the links I, pivoted to the lever, andan adjustable connection between `the cranks and` links, all arranged and adapted to operate substantially as 'herein described.

In witness'whereof I have hereunto set my` hand.
